C0455 Description

 

The Electronic Brake Control Module (EBCM) receives several inputs from the steering wheel position sensor. Three digital square wave signal inputs are wired directly to the EBCM harness connector, however, only signals A and B are used or monitored. The failure of the index pulse signal does not effect vehicle Stability Enhancement System (VSES) function. The EBCM also receives an analog steering wheel position input on the steering wheel position sensor signal 1 circuit. Ignition voltage is supplied to the digital portion of the steering wheel position sensor. The analog portion of the steering wheel position sensor is supplied a 5-volt reference from the EBCM.
